The security alarm can be subtly deceiving and lock out the owner with a fuel cut-off switch if it's been activated. If the battery or anything else that triggers the security system has been activated especially after sitting and changing the battery, it will shut off the electric fuel pump with a cut-off relay. Take off the ground for the battery for a few minutes, then put it back on and your flashers should be blinking. Then use the key to the left and to the right in the driver's door and/or the rear hatch. One of them should make the flashers stop, and the vehicle may then start. You can also ground the purple and black wire to the alarm near your left foot in the kick plate by the parking brake.

I've done everything, ground the purple and black wire from the security box, turn the key back and forth on the passenger side door, disconnected the security box under the glove box, etc...

My jeep is old, been through a lot. But I want to get it started. When I turn it over it will "catch" for a second, and then it will shut off. Is there any way to go straight to the source and shut the security system off. Mine keeps flashing. And sometimes if I leave it flashing it will stop after a while. But still does the same thing.

Can anyone help me and tell me what to do in a simple step by step fashion?

Did you ever figure out why it wouldn't run? Mine does the same thing - runs for a few seconds and then gets shutdown. I've changed numerous sensors and tested others(about a dozen things). Can't figure it out. I know your post is old, but I was hoping you would get this message and be able to respond with a solution based on your trouble.

I have a 1997 jeep grand cherokee that our son ditched in a ditch of water on the drivers side. We changed all fluids, new battery. The dash lights do not work and the battery runs down unless you unhook it. It does not want to idle, you have to keep foot on the gas and brake, but it fires right up . All the lighting, headlights and turn and signals are broken out but the drivers headlight which works. We are replacing them today. I am guessing the main computer is okay because it does fire up when you hook the battery up and with the anti theftlock I was told it would'nt if the main computer was on the fritz. My question is, what do I need to make those dashlights work and to make it quit draining the battery and idle better? Please help. No jeep dealer close here. Also if it is a wiring harness or dash module of some sort, will replacing that set off the anti theft lock and shut it all down? Is there a way to disable this stupid system? thanks tina/94tomtom

well kevin i bought my daughters 95 cherokee sport after the the key switch burnt up.wehn i got it home i changed the key switch tried to start it,it turned over but no start.ah check out the fuel.no fuel oh nooo 96.more dollars,but after pulling the gas tank and checking the fuel pump its working.but it wouldnt pump.i asked the local jeep mech what could cause this,his eyes rooled back in his head duh i dont know.fuel ,no i said it runs .so after 3 months of cussing and discust.i searched the internet and came across this cnet forum about the anti thieft cutout.well i tried this and turned the key in the hatch and it started mutch to my amazement and i didnt even know it had anti thieft so now i will drive a jeep now.amen

can you please tell me what is the way of doing to be able to read Flashing code on my grand cherokee 1995.I think the instrument is in under the glove compartment but past that i don't know what to do.

To access your codes (Jeep 1990-1995) Turn the ignition on off on off and on (don't turn it over) leave the ignition on, the check engine light will turn off or be off, then it will flash numbers for code, all the codes are two digits, the first number will flash once for a one or twice for two and so on, then there will be a significant pause between the first and second digit, then longer pauses between codes. If the pcm (powertrain control module) is funtioning properly then when transmission of all codes is complete, it will flash 55, so five flashes followed by five flashes. codes range from 10-60 more or less. 12 means the pcm has been cleared within 50-100 starts, for codes see http://www.webejeepin.com/Check-Engine.htm this should be good for 1990-1995 jeeps.

For the trouble starting, my 1995 Jeep Cherokee had the problem where it needed to be started in neutral and progressed worse to needing to be jossled or cranked several times to start after clicking and not turning over. I had the starter tested and the starter was OK. The mechanic said it was the neutral safety switch on the transmission and also likely the starter. At its worst the Jeep wouldn't start but after jossling the starter, removing/replacing the starter, and adjusting the bolt on the neutral safety switch would make it start easier temporarily.

Hey thanks for the info!! i was finally able to retreive the code information it was 12 seems like the guy i bought it for might of unpluged the battery i don't know if it's possible that he was trying to erase the old code by doing that .in result I still dont know what's wrong w/ the box beside my shifter; it always indicate me that all my doors are opened by flashing some light in the diagram of that same box. Witch isn't the case.can you please help me on that? Thanks in advance.

can someone show a photo where the crank sensor is. today my 95 grand would start i used startung fluid still no joy.pulled a spark wire and no spark and no voltage at the coil.this is my wifes car i need it running. thanks

We inherited a 1995 Jeep Cheroke Ltd. Ed. from a family member. Everything has been great so far, the vechicle has been checked over, all is good. The other night I drove home and parked, nothing strange. The next day... dead, completely, won't turn over. When my husband tried to give me a boost, all the lights flash, headlights, dash, interior, clock resets to Jan 01 and a light on the dash that says security comes on... the Jeep turns over but does not seem to "catch." I was told to try to unlock the doors with the remote lock system but that has never worked since I got the vehicle... I don't want to call a tow truck... there is no Jeep dealership in town... is there something we are missing here? Any advice would be GREATLY appreciated!

after having for a while the jeep would run for a few blocks then cut off like some one turned off the key. Most times it would start right back up but on occasion it would take a bit, also noticed sometimes when driving it would act like it was trying to cut off but if I give it gas real quick it wont die, it makes a knock when it does this. HELP PLEASE

I have a 99 grand cherokee laredo that was attempted to be stolen. you now haVE TO start the vehicle with a screwdriver. now the jeep starts but shuts its self off after about 3 seconds. is there any way to bypass this anti-theft system?

I think you are on the right track with the pick-up module, but go 1 step further and blow out the distributor base plate, rotor and cap with air and wipe out with clean rag. the residual dust that occurs naturally from sparks and heat can keep a perfectly good module from working. I have had this happen twice in last several years on my 95 in-line 6 cyl. First time I replaced and cleaned, last 2 times I just cleaned good. Worth a try! Ken

Changed crankshaft sensor, coil, ecm, it has very little spark at the coil. It cranks, timing is OK, turns over as it should, still gives very weak spark at the coil which is new....?????1995 jeep grand cherokee

I use my jeep to deliver mail on a rural route. It has over 300,000 miles and when it's hot outside, after my jeep has been running a while, it will just cut off. It has cut off when I am sitting still and going down the interstate. I just had a fuel pump put on it, my husband replaced the fuel filter, the gas tank is full, it's getting a spark...the computer at the shop shows nothing. When it's moving and cuts off, it sputters like it's not getting gas or running out of gas. Sometimes it will crank right back up and sometimes, it's a hour. We don't know what to do and I use this car for work, can someone help? It's a 6cyl, 4.0 liter automatic engine. Thanks!

check if yo have voltage going to your ecm should have 12v. on terminals from switch. then if curretn is then go to ignition module. you should have battery voltage.if not replace ecm. if voltage available replace module, but check wiring and terminals as well. grounds, etc. remember you should start by the basics, and don't jump to conclusions. this is the quickiest way to spend on unnecessary parts.

Did you ever figure out why it wouldn't run? Mine does the same thing - runs for a few seconds and then gets shutdown. I've changed numerous sensors and tested others(about a dozen things). Can't figure it out. I know your post is old, but I was hoping you would get this message and be able to respond with a solution based on your trouble.

Before you go anyfurtherr, did you checked for spark at the spark plugs, then is there voltage from the ecm? is there fuel going to the injectors? go back to the basics. forget about the codes until you're sure you have spark, fuel and air going to the cylinders, you still have an engine despite having fuel injection, an EGR will cause it to stall and run rich, on very extreme cases, won't start, the eccm on Chrisler products, aren't exactly the best. and, if you dont have current coing to the distributor 8 out of 10 the ecm is the culprit.I was a driveability tech specialized on GM products. but I diagnosed Ford and Chryslers as well and based on experience check your leads going to the distributor for voltage, check the distributor, that will give you a better picture of what's going on with yyour Jeep.

Thanks for your quick respones. I've checked all of those things and they work.

Think about this - - the jeep will run when I spray starting fluid into the throttle body. I can jump the fuel pump relay to keep it running all the time(I can hear it).but it won't run if I stop spraying fuel into the throttle body. The fuel pressure is 40 psi( which is correct). The fuel pressure regulator is new. It seems to me that something is shutting down the fuel injectors, while spark and everything else is still working. The question is what can do that. Any ideas?

just happened to me this week. i have a 2000 jeep cherokee. the gauges werent moving, would turn over but not start. it was the crank shaft position sensor. about $250 to fix, only a couple hrs. hope this helps!

My jeep will just shut off in the middle of driving . The guage don't register and the key with a cross through it lights up on my panel. I take the key out and put it back in a number of times and when the guages register my jeep will start. I was wondering if it's my anti theft shutting my jeep down. Any suggestions?
